Venture capital poured $12 billion into developer tools in 2025, the highest ever for the category. AI-powered coding, observability, and infrastructure platforms are dominating funding rounds.
Biggest Rounds
- Cursor (AI coding): $400M Series B at $2.5B valuation
- Vercel (frontend platform): $250M at $3.5B
- Supabase (open-source Firebase): $80M Series C
- Railway (infrastructure): $40M Series B
The thesis: developers are the new economic bottleneck, and tools that make them 2-5x more productive command premium valuations. AI code assistants alone received $4B of the $12B total.
